Description

Technical Field

[0001] The invention relates to a horizontal continuous casting rod collecting device, in particular to a vertical casting rod collecting machine. Background Art

[0002] During the production of cast rods using horizontal continuous casting equipment, the cast rods need to be collected and arranged in circles in order to carry out subsequent processing such as cast rod drawing. Existing horizontal continuous casting equipment generally uses one or more heads for traction, and the specific number of heads is related to the specifications of the cast rods. When multiple cast rods are continuously cast at the same time, each cast rod needs to be equipped with a collection device. Multiple collection devices are laid out in sequence at the production site, occupying a large area, which is not conducive to space saving and has certain safety hazards. In addition, existing collection devices often use an ordinary motor to drive the rotating shaft, connecting the material rack to the rotating shaft, and the rotation of the motor drives the rotation of the material rack to achieve the collection of the cast rods. Since the speed of the motor is uncontrollable, the diameter of the circle material after collection is unstable, which affects the subsequent processing quality and processing efficiency of the cast rods. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a vertical cast rod coiling machine in response to the shortcomings of the existing technology. The coiling machine can effectively reduce the floor space of the coiling machine, save workshop space, and reduce safety risks. At the same time, it can realize the integrated automatic operation of traction, bending, and coiling, ensuring that the coil diameter obtained by coiling is stable, which is conducive to improving the subsequent processing quality and processing efficiency of cast rods.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a vertical cast rod coiling machine, including a base plate, a column, a pole, multiple coiling units, multiple coiling units and a traction unit, the column and the pole are respectively fixed vertically on the base plate, the multiple coiling units are installed on the column at intervals up and down, each of the coiling units includes a rotating arm, a first drive unit, a second drive unit and a material tray, the rotating arm is rotatably connected to the column, the rotation of the rotating arm is driven by the first drive unit, the material tray is rotatably connected to the rotating arm, the rotation of the material tray is driven by the second drive unit, The multiple looping units are installed on the vertical pole at intervals above and below, and each of the looping units is opposite to a looping unit. Each of the looping units is used to continuously bend a cast rod. The traction unit is located at the front side of the multiple looping units. The traction unit is used to simultaneously pull multiple cast rods obtained by horizontal continuous casting to multiple looping units. Each looping unit continuously bends a cast rod and then sends it into a material tray. Through the rotation of multiple material trays, multiple cast rods can be looped at the same time. When the loop material on a certain material tray needs to be removed, the corresponding rotating arm is rotated to a certain angle through the corresponding first driving unit to perform the material moving operation.

[0005] The cast rod coiling machine of the present invention adopts a vertical layered structure. Through multiple coiling units spaced apart at upper and lower intervals, it can realize the simultaneous coiling of multiple cast rods. While ensuring production efficiency, it can effectively reduce the floor space of the coiling machine, save workshop space, and reduce safety risks. In addition, the multiple cast rods obtained by horizontal continuous casting are simultaneously pulled to multiple coiling units in conjunction with the traction unit. The coiling units continuously bend them and then feed them into the material tray for coiling, realizing the integrated automatic operation of traction, bending, and coiling. It can ensure that the coil diameter obtained by coiling is stable, which is conducive to improving the subsequent processing quality and processing efficiency of the cast rods.

During the looping process, each cast rod is continuously bent while passing through the gap between the active pressure wheel, the driven pressure wheel, and the tensioning wheel of each looping unit. The active pressure wheels of multiple looping units are controlled by the same servo motor, which can ensure the synchronous and continuous bending effect of multiple cast rods during the looping process and ensure the circle diameter of the coiled material after looping.

During the coiling process, the second reducer works, driving the second gear to rotate through the second pinion, thereby driving the material tray to rotate, thereby achieving coiling and coiling of the cast rod. The second reducer cooperates with the first servo motor and the first reducer to realize the speed adjustment of bending and coiling. At the same time, the speed can be adjusted from fast to slow or from slow to fast, thereby obtaining a flat Archimedean spiral-shaped coil material to meet subsequent different production needs and better serve production and processing.

[0013] Preferably, the second reducer is a single-stage cycloid pinwheel reducer.
